o Minor bugfixes:
    - Detect and reject certain misformed escape sequences in configuration
      values. Previously, these values would cause us to crash if received
      in a torrc file or over an (authenticated) control port. Bug found by
      Esteban Manchado Velázquez. Patch by Alexander Schrijver. Fix for
      bug 5090; bugfix on 0.2.0.16-alpha.
